Updated: Jan. 20, 2023
The oceans truly contain countless mysteries.
They say still waters run deep, but ocean waves hide the strangest things
It goes without saying that the world’s oceans are vast and mysterious. Therefore, it is no surprise that people have found some truly strange things when exploring them. From ancient statues to war artifacts to weird underwater life forms, here are the strangest things found by deep-sea divers. Make sure you also check out these amazing trivia facts about the earth’s oceans.
Trucks
Trucks belong on the road—but some of them manage to make their way to the bottom of the ocean. It’s not unusual for deep-sea divers to occasionally stumble upon artifacts of military trucks within the ocean’s depths. Here are some strange facts about the earth you never learned in school.
Planes
Just like trucks, planes occasionally find their way to the bottom of the ocean. For example, deep-sea divers in Oahu, Hawaii, stumbled upon the remains of an F4U Corsair that had been in many wars and crashed into the ocean in 1946 due to fuel shortage. Here are some of the most beautiful sea caves in the world to visit.
Ferries
An Underwater River
The Underwater River is not actually a river, but an optical illusion. Cenote Angelita Cave contains a very rare optical illusion, caused by a halocline: a cloud of hydrogen sulphide formed by decomposing organic debris at the bottom of the cave. This magical-looking cloud separates the salty seawater above from the fresh groundwater which seeps up from below, and makes it seem like divers are swimming in an underwater river.

Statues
Museums are not the only place you can find historical relics. If they’re lucky, deep-sea divers occasionally run into submerged ancient statues. For example, on the seafloor off the coast of Naples, Italy, lies one of the world’s only underwater archaeological parks: the ruins of the ancient Roman city of Baia. Here are some other incredible undersea treasures found all around the world.
Tanks
Reminders of past wars can make their way anywhere—and that includes oceans. Deep-sea divers occasionally end up finding remains of once-powerful tanks at the bottom of the ocean. Here are some other technological advancements from World War I.
Gas masks
It is not exactly a joyous occasion to run into masks used in past wars on the bottom of the ocean. However, deep-sea divers do occasionally run into forgotten war relics like these. Did you know gas masks are not the only creepy things you can find in the depths of the ocean?
Titanic
Yes, the ruins of the famous Titanic were never recovered. The once “unsinkable” ship lies at the bottom of the Atlantic Ocean, and it was discovered in September 1985. Fascinated by shipwrecks? Check out these other sunken ships around the world.
Jesus statue
A glorious sculpture of Jesus Christ by Guido Galletti was deliberately placed on the Mediterranean seabed in 1954. The status is a tribute to Italian scuba diver Dario Gonzatt, who had died while diving in that location, near the Italian Riviera. Today, divers find the statue covered by ocean life.

Giant Isopod
Christmas tree worm
This strange yet beautiful deep-sea creature was found by scientists at the Great Barrier Reef’s Lizard Island. Although they get their name from their triangular plumes, this colorful creature would make a great addition to any Christmas tree–but they’d prefer a coral tree.
Sea angels
With their beautiful, nearly transparent wings, it’s easy to see where sea angels get their name, but they are actually a type of predatory sea snail. Unlike other sea snails, sea angels don’t have shells. They grow no bigger than a walnut (about 2 inches).
